My System Specs

Default Adding a second 7970. Need some advice.

Ok guys, I ordered a second 7970. I'm going to run it on air for a while until I get this stuff figured out and acquire everything I'll need to add it to my existing loop.

This is what my setup looks like right now.

The second 7970 will be going where the sound card is for dual x16 operation, and the sound card will be moved up to either the x1 slot under the top the card or the second x16 slot (which will only run at x8 if used in crossfire).

Anyhow, down to my questions......

1 - Should I run the the water through the video card waterblocks in serial or parallel?

2 - Will I need another rad? My temps are excellent right now. CPU doesn't break 45*C, GPU tops out at 47*C, and mobo hovers around 35*C. I can add a 120 rad at the rear if I have to.

3 - Will my pump be adequate for the added components? I'm running an EK-DCP 4.0 which is capable of pushing 800L/hour.

4 - Are the new EK CSQ blocks any better then the old ones? I'd like to run two of the same blocks mainly for aesthetics, but I can't find one the same as I currently have..... kinda bums me out.

Thanks in advance!
